Conferences and Journals

The radiation processing industry holds a biennial conference under the title IMRP (International Meeting on Radiation Processing) under the umbrella of an industry association called IIA (International Irradiation Association). Proceedings of papers presented are normally published in the Journal, Radiation Physics and Chemistry.

Plants Worldwide

The following table and chart summarize results of a study carried out by I-Ax Technologies Inc several years ago.

Region	Number	Number of 10 MeV	Number of 5 MeV	Number of 3 MeV	Sterilization	Food	Other
North America	24	15	8	2	14	7	12
Europe	37	28	9	0	20	1	21
Asia	10	5	3	2	8	0	7
World	71	48	20	4	42	8	40

Note: Since dual-mode and multipurpose plants are included totals do not necessarily agree.

Figure 1: Year of installation of accelerators.

Together they represent a power of 2,984 kilowatts or the equivalent of 199 Megacuries of cobalt. Installations by year show no systematic trend (see Figure 1). They have been built by 24 different manufacturers, of which only 12 are currently active.
